|
||||
# Changelog
|
||||
# 0.01 - Initial version
|
||||
# 0.02 - Huffdic compressed books were not properly decrypted
|
||||
# 0.03 - Wasn't checking MOBI header length
|
||||
# 0.04 - Wasn't sanity checking size of data record
|
||||
# 0.05 - It seems that the extra data flags take two bytes not four
|
||||
# 0.06 - And that low bit does mean something after all :-)
|
||||
# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
|
||||
# 0.08 - ...and also not in Mobi header version < 6
|
||||
# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
|
||||
# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
|
||||
# import filter it works when importing unencrypted files.
|
||||
# Also now handles encrypted files that don't need a specific PID.
|
||||
# 0.11 - use autoflushed stdout and proper return values
|
||||
# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
|
||||
# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
|
||||
# and extra blank lines, converted CR/LF pairs at ends of each line,
|
||||
# and other cosmetic fixes.
|
||||
# 0.14 - Working out when the extra data flags are present has been problematic
|
||||
# Versions 7 through 9 have tried to tweak the conditions, but have been
|
||||
# only partially successful. Closer examination of lots of sample
|
||||
# files reveals that a confusion has arisen because trailing data entries
|
||||
# are not encrypted, but it turns out that the multibyte entries
|
||||
# in utf8 file are encrypted. (Although neither kind gets compressed.)
|
||||
# This knowledge leads to a simplification of the test for the
|
||||
# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
|
||||
# 0.15 - Now outputs 'heartbeat', and is also quicker for long files.
|
||||
# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
|
||||
# 0.17 - added modifications to support its use as an imported python module
|
||||
# both inside calibre and also in other places (ie K4DeDRM tools)
|
||||
# 0.17a- disabled the standalone plugin feature since a plugin can not import
|
||||
# a plugin
|
||||
# 0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
|
||||
# Removed the disabled Calibre plug-in code
|
||||
# Permit use of 8-digit PIDs
|
||||
# 0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
|
||||
# 0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
|
||||
# 0.21 - Added support for multiple pids
|
||||
# 0.22 - revised structure to hold MobiBook as a class to allow an extended interface
|
||||
# 0.23 - fixed problem with older files with no EXTH section
|
||||
# 0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
|
||||
# 0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
|
||||
# 0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
|
||||
# 0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
|
||||
# 0.28 - slight additional changes to metadata token generation (None -> '')
|
||||
# 0.29 - It seems that the ideas about when multibyte trailing characters were
|
||||
# included in the encryption were wrong. They are for DOC compressed
|
||||
# files, but they are not for HUFF/CDIC compress files!
|
||||
# 0.30 - Modified interface slightly to work better with new calibre plugin style
|
||||
# 0.31 - The multibyte encrytion info is true for version 7 files too.
|
||||
# 0.32 - Added support for "Print Replica" Kindle ebooks

||||
|
||||

# Changelog
|
||||
# 0.01 - Initial version
|
||||
# 0.02 - Huffdic compressed books were not properly decrypted
|
||||
# 0.03 - Wasn't checking MOBI header length
|
||||
# 0.04 - Wasn't sanity checking size of data record
|
||||
# 0.05 - It seems that the extra data flags take two bytes not four
|
||||
# 0.06 - And that low bit does mean something after all :-)
|
||||
# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
|
||||
# 0.08 - ...and also not in Mobi header version < 6
|
||||
# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
|
||||
# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
|
||||
# import filter it works when importing unencrypted files.
|
||||
# Also now handles encrypted files that don't need a specific PID.
|
||||
# 0.11 - use autoflushed stdout and proper return values
|
||||
# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
|
||||
# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
|
||||
# and extra blank lines, converted CR/LF pairs at ends of each line,
|
||||
# and other cosmetic fixes.
|
||||
# 0.14 - Working out when the extra data flags are present has been problematic
|
||||
# Versions 7 through 9 have tried to tweak the conditions, but have been
|
||||
# only partially successful. Closer examination of lots of sample
|
||||
# files reveals that a confusion has arisen because trailing data entries
|
||||
# are not encrypted, but it turns out that the multibyte entries
|
||||
# in utf8 file are encrypted. (Although neither kind gets compressed.)
|
||||
# This knowledge leads to a simplification of the test for the
|
||||
# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
|
||||
# 0.15 - Now outputs 'heartbeat', and is also quicker for long files.
|
||||
# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
|
||||
# 0.17 - added modifications to support its use as an imported python module
|
||||
# both inside calibre and also in other places (ie K4DeDRM tools)
|
||||
# 0.17a- disabled the standalone plugin feature since a plugin can not import
|
||||
# a plugin
|
||||
# 0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
|
||||
# Removed the disabled Calibre plug-in code
|
||||
# Permit use of 8-digit PIDs
|
||||
# 0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
|
||||
# 0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
|
||||
# 0.21 - Added support for multiple pids
|
||||
# 0.22 - revised structure to hold MobiBook as a class to allow an extended interface
|
||||
# 0.23 - fixed problem with older files with no EXTH section
|
||||
# 0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
|
||||
# 0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
|
||||
# 0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
|
||||
# 0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
|
||||
# 0.28 - slight additional changes to metadata token generation (None -> '')
|
||||
# 0.29 - It seems that the ideas about when multibyte trailing characters were
|
||||
# included in the encryption were wrong. They are for DOC compressed
|
||||
# files, but they are not for HUFF/CDIC compress files!
|
||||
# 0.30 - Modified interface slightly to work better with new calibre plugin style
|
||||
# 0.31 - The multibyte encrytion info is true for version 7 files too.

# 0.32 - Added support for "Print Replica" Kindle ebooks

\cf0 DeDRM_X.X is an AppleScript droplet that allows users to drag and drop ebooks or folders of ebooks onto the DeDRM droplet to have the DRM removed. It repackages the all the "tools" DeDRM python software in one easy to use program that remembers preferences and settings.\
|
||||
\
|
||||
It should work without manual configuration with Kindle for Mac ebooks and Adobe Adept epub and pdf ebooks.\
|
||||
\
|
||||
To remove the DRM from standalone Kindle ebooks, eReader pdb ebooks, Barnes and Noble epubs, and Mobipocket ebooks requires the user to double-click the DeDRM droplet and set some additional Preferences including:\
|
||||
\
|
||||
Kindle 16 digit Serial Number\
|
||||
Barnes & Noble key files (bnepubkey.b64)\
|
||||
eReader Social DRM: (Name:Last 8 digits of CC number)\
|
||||
MobiPocket, Kindle for iPhone/iPad/iPodTouch 10 digit PID\
|
||||
Location for DRM-free ebooks.\
|
||||
\
|
||||
Once these preferences have been set, the user can simply drag and drop ebooks onto the DeDRM droplet to remove the DRM.\
|
||||
\
|
||||
This program requires Mac OS X 10.5, 10.5 or 10.7 (Leopard, Snow Leopard or Lion)
\

I strongly recommend fully installing ActiveState’s Active Python, free Community Edition for Windows (x86) 32 bits. This is a free, full version of the Python. It comes with some important additional modules that are not included in the bare-bones version from www.python.org unless you choose to install everything.
|
||||
|
||||
1. Download ActivePython 2.7.1 for Windows (x86) (or later 2.7 version for Windows (x86) ) from http://www.activestate.com/activepython/downloads. Do not download the ActivePython 2.7.1 for Windows (64-bit, x64) verson, even if you are running 64-bit Windows.
|
||||
1. Download ActivePython 2.7.X for Windows (x86) (or later 2.7 version for Windows (x86) ) from http://www.activestate.com/activepython/downloads. Do not download the ActivePython 2.7.X for Windows (64-bit, x64) verson, even if you are running 64-bit Windows.
|
||||
|
||||
2. When it has finished downloading, run the installer. Accept the default options.

Installing PyCrypto on Windows
|
||||
------------------------------
|
||||
PyCrypto is a set of encryption/decryption routines that work with Python. The sources are freely available, and compiled versions are available from several sources. You must install a version that is for 32-bit Windows and Python 2.7. I recommend the installer linked from Michael Foord’s blog.

Kindle for iPhone, iPod Touch, iPad

The Kindle application for iOS (iPhone/iPod Touch/iPad) uses a PID derived from the serial number of the iPhone/iPod Touch/iPad. Kindlepid.pyw (see Other_Tools/Additional_Tools) is a python script that turns the serial number into the equivalent PID, which can then be used with the Calibre Plugins and DeDRM Applications.

The Kindle application for iOS (iPhone/iPod Touch/iPad) uses a PID derived from the serial number of the iPhone/iPod Touch/iPad. Kindlepid.py is a python script that turns the serial number into the equivalent PID, which can then be used with the MobiDeDRM script.
|

So, to remove the DRM from (Mobipocket) Kindle books downloaded to your iPhone/iPodTouch/iPad, you’ll need the latest toolsvx.x.zip archive and
|
||||
So, to remove the DRM from (Mobipocket) Kindle books downloaded to your iPhone/iPodTouch/iPad, you’ll need the latest tools_vX.X.zip archive and
|
||||
some way to extract the book files from the backup of your device on your computer. There are several free tools around to do this.
|
||||
|
||||
Double-click on KindlePID.pyw to get your device’s PID, then use the extractor to get your book files, then double-click on MobiDeDRM.pyw with the PID and the files to get Drm-free versions of your books.
|
||||
Your first step is to download and install one of the free apps onto your iPod Touch/iPhone/iPad that will find your devices's UUID. Alternatively, you can find your device's UDID in iTunes when your device is connected in the Summary page – click on the serial number and it changes to the (40 digit!) UDID.
|
||||
|
||||
Kindlefix gives you another way to use the PID generated by kindlepid. Some ebook stores and libraries will accept the PIDs generated by kindlepid (some won’t), and you can then download ebooks from the store or library encrypted to work with your Kindle. Except they don’t. There’s a flag byte set in encrypted Kindle ebooks, and Kindles and the Kindle app won’t read encrypted mobipocket ebooks unless that flag is set. Kindlefix will set that flag for you. If your library have Mobipocket ebooks to lend and will accept your Kindle’s PID, you can now check out library ebooks, run kindlefix on them, and then read them on your Kindle, and when your loan period ends, they’ll automatically become unreadable.
|
||||
|
||||
To extract the files from your iPod Touch (not archived Kindle ebooks, but ones actually on your iPod Touch) it’s necessary to first do a back-up of the iPod Touch using iTunes. That creates a backup file on your Mac, and you can then extract the Mobipocket files from that using iPhone/ipod Touch Backup Extractor – free software from here: http://supercrazyawesome.com/
|
||||
|
||||
Ok, so that will get your the .azw Kindle Mobipocket files.
|
||||
|
||||
Now you need the PID used to encrypt them. To get that you’ll need your iPod Touch UDID number – you can find it in iTunes when your iPod Touch is connected in the Summary page – click on the serial number and it changes to the (40 digit!) UDID.
|
||||
|
||||
And then you need to double-click the KindlePID.pyw script and enter your 40 digit UDID in the window and hit "Start".
|
||||
|
||||
and you should get back a response something like:
|
||||
Once you have the UUID, double-click on KindlePID.pyw to get your device’s PID.
|
||||
You should get back a response something like:

iPhone serial number (UDID) detected
|
||||
Mobipocked PID for iPhone serial# FOURTYDIGITUDIDNUMBERGIVENHERE is TENDIGITPID
|
||||
|
||||
which gives you the PID to be used with MobiDeDRM to de-drm the files you extracted.
|
||||
You can then add this fixed PID to the DeDRM Applications or Calibre_Plugins or KindleBooks tools and be ready to go.
|
||||
|
||||
You next need to find an "iPhone Extractor" or "iPhone Explorer" program for your OS that will allow you to mount your iPhone/iPad/iPod Touch as a usb device on your machine and copy your Kindle ebooks from the device back to your home machine.

Welcome to the tools!
|
||||
|
||||
The set includes tools to remove DRM from eReader PDB books, Barnes and Noble ePubs, Adobe ePubs, Adobe PDFs, and Kindle/Mobi ebooks (including Topaz).
|
||||
|
||||
=====================
|
||||
|
||||
This ReadMe_First.txt is meant to give users a quick overview of what is available and how to get started.
|
||||
|
||||
The is archive includes tools to remove DRM from:
|
||||
- eReader PDB books
|
||||
- Barnes and Noble ePubs
|
||||
- Adobe Digitial Editions ePubs
|
||||
- Adobe Digitial Editions PDFs
|
||||
- Kindle/Mobipocket ebooks (including Topaz, Print Replica and KF8).
|
||||
|
||||
Calibre Users (Mac OS X, Windows)
|
||||
-------------
|
||||
If you are a calibre user, the quickest and easiest way to remove DRM from your ebooks is to open the Calibre_Plugins folder and install each of the plugins following the instructions and configuration directions provided in each plugins README file.
|
||||
These tools do NOT work with Apple's iBooks FairPlay DRM.
|
||||
|
||||
Once installed and configured, you can simply import a DRM book into Calibre and end up with the DeDRM version in the Calibre database.
|
||||
The only tool that removes Apple's iBooks Fairplay DRM that is Requiem by Brahms version 3.3 or later. Requiem is NOT included in this tools package. It is under active development because Apple constantly updates its DRM scheme to stop Requiem from working.
|
||||
|
||||
These plugins work for Windows and Mac OS X
|
||||
Requiem has a Tor website: http://tag3ulp55xczs3pn.onion. To reach the site using Tor, you will need to install Tor (http://www.torproject.org). If you're willing to sacrifice your anonymity, you can use the regular web with tor2web. Just go to http://tag3ulp55xczs3pn.tor2web.com.
|
||||
|
||||
|
||||
|
||||
Mac OS X Users (Mac OS X 10.5, 10.6, and 10.7)
|
||||
--------------
|
||||
From the DeDRM_for_Mac_and_Win folder, drag the DeDRM_X.X.app.zip droplet to your Desktop. Double-click on it once to unzip it to create the DeDRM X.X.app droplet. Double-click on the droplet once and it will guide you through collecting the data it needs to remove the DRM.
|
||||
Calibre Users (Mac OS X, Windows, and Linux)
|
||||
--------------------------------------------
|
||||
If you are a calibre user, the quickest and easiest way to remove DRM from your ebooks is to open the Calibre_Plugins folder and install each of the plugins following the instructions and configuration directions provided in each plugins' README file.
|
||||
|
||||
To use it simply drag a book onto the droplet and it will process the book. This tools supports dragging and dropping of folders of ebooks as well.
|
||||
Once installed and configured, you can simply add a DRM book to calibre and the DeDRM version will be imported into the calibre database. Note that DRM removal ONLY occurs on import. If you have already imported DRM books you'll need to remove them from calibre and re-import them.
|
||||
|
||||
These plugins work for Windows and Mac OS X. All plugins (including the K4MobiDeDRM plugin when used on books from Kindle for PC under wine) should also work on Linux. Linux users should read the section at the end of this ReadMe.
|
||||
|
||||

||||
|
||||
Windows Users (Xp through Windows 7)
|
||||
--------------

Not a Calibre or a DeDRM User?
|
||||
------------------------------
|
||||
There are a number of python based tools that have graphical user interfaces to make them easy to use. To use any of these tools, you need to have Python 2.5, 2.6, or 2.7 for 32 bits installed on your machine as well as a matching PyCrypto or OpenSSL for some tools.

Other_Tools
|
||||
-----------
|
||||
There are a number of other python based tools that have graphical user interfaces to make them easy to use. To use any of these tools, you need to have Python 2.5, 2.6, or 2.7 for 32 bits installed on your machine as well as a matching PyCrypto or OpenSSL for some tools.
|
||||
|
||||
On Mac OS X (10.5, 10.6 and 10.7), your systems already have the proper Python and OpenSSL installed. So nothing need be done, you can already run these tools by double-clicking on the .pyw python scripts.
|
||||
|
||||
Users of Mac OS X 10.3 and 10.4, need to download and install the "32-bit Mac Installer disk Image (2.7.X) for OS X 10.3 and later from http://www.python.org/download/releases/2.7.1/
|
||||
|
||||
On Windows, you need to install a 32 bit version of Python (even on Windows 64) plus a matching 32 bit version of PyCrypto *OR* OpenSSL. We ***strongly*** recommend teh free ActiveState's Active Python version. See the end of this document for details.

Some additional tools are also provided in the "Mobi_Additional_Tools" folder. There are tools for working with "Kindle for iPhone/iPod_Touch/iPad", finding Topaz ebooks, unpacking Mobi ebooks (without DRM) to get to the Mobi markup language inside, and etc.
|
||||
|
||||
There is also an "ePub_Fixer" folder that can be used to fix broken DRM epubs that sometimes re provided by Adobe and Barnes and Noble that actually violate the zip/epub standard.

Windows and Python Tools
|

------------------------
|

Windows and Python
|
||||
------------------
|
||||
We **strongly** recommend ActiveState's Active Python 2.7 Community Edition for Windows (x86) 32 bits. This can be downloaded for free from:
|
||||
|
||||
http://www.activestate.com/activepython/downloads
|
||||
|
||||
We do **NOT** recommend the version of Python from python.org.
|
||||
The version from python.org is not as complete as most normal Python installations on Linux and even Mac OS X. It is missing various Windows specific libraries, does not install the default Tk Widget kit (for guis) unless you select it as an option in the installer, and does not properly update the system PATH environment variable. Therefore using the default python.org build on Windows is simply an exercise in frustration for most Windows users.

Linux Users Only
|
||||
================
|
||||
|
||||
Since Kindle for PC and Adobe Digital Editions do not offer native Linux versions, here are instructions for using Windows versions under Wine as well as related instructions for the special way to handle some of these tools:
|
||||
|
||||
|
||||
Linux and Kindle for PC (Other_Tools/KindleBooks/)
|
||||
--------------------------------------------------
|
||||
|
||||
Here are the instructions for using Kindle for PC and KindleBooks.pyw on Linux under Wine. (Thank you Eyeless and Pete)
|
||||
|
||||
1. upgrade to very recent versions of Wine; This has been tested with Wine 1.3.15 – 1.3.2X. It may work with earlier versions but no promises. It does not work with wine 1.2.X versions.
|
||||
|
||||
If you have not already installed Kindle for PC under wine, follow steps 2 and 3 otherwise jump to step 4
|
||||
|
||||
2. Some versions of winecfg have a bug in setting the volume serial number, so create a .windows-serial file at root of drive_c to set a proper windows volume serial number (8 digit hex value for unsigned integer).
|
||||
cd ~
|
||||
cd .wine
|
||||
cd drive_c
|
||||
echo deadbeef > .windows-serial
|
||||
|
||||
Replace "deadbeef" with whatever hex value you want but I would stay away from the default setting of "ffffffff" which does not seem to work. BTW: deadbeef is itself a valid possible hex value if you want to use it
|
||||
|
||||
3. Only ***after*** setting the volume serial number properly – download and install under wine K4PC version for Windows. Register it and download from your Archive one of your Kindle ebooks. Versions known to work are K4PC 1.7.1 and earlier. Later version may work but no promises.
|
||||
|
||||
4. Download and install under wine ActiveState Active Python 2.7 for Windows 32bit
|
||||
|
||||
5. Download and unzip tools_vX.X.zip
|
||||
|
||||
6. Now make sure the executable bit is NOT set for KindleBooks.pyw as Linux will actually keep trying to ignore wine and launch it under Linux python which will cause it to fail.
|
||||
|
||||
cd tools_vX.X/KindleBooks/
|
||||
chmod ugo-x KindleBooks.pyw
|
||||
|
||||
7. Then run KindleBook.pyw ***under python running on wine*** using the Linux shell as follows:
|
||||
|
||||
wine python KindleBooks.pyw
|
||||
|
||||
Select the ebook file directly from your “My Kindle Content” folder, select a new/unused directory for the output. You should not need to enter any PID or Serial Number for Kindle for PC.

Linux and Adobe Digital Editions ePubs
|
||||
--------------------------------------
|
||||
|
||||
Here are the instructions for using the tools with ePub books and Adobe Digital Editions on Linux under Wine. (Thank you mclien!)
|
||||
|
||||
|
||||
1. download the most recent version of wine from winehq.org (1.3.29 in my case)
|
||||
|
||||
For debian users:
|
||||
|
||||
to get a recent version of wine I decited to use aptosid (2011-02, xfce)
|
||||
(because I’m used to debian)
|
||||
install aptosid and upgrade it (see aptosid site for detaild instructions)
|
||||
|
||||
|
||||
2. properly install Wine (see the Wine site for details)
|
||||
|
||||
For debian users:
|
||||
|
||||
cd to this dir and install the packages as root:
|
||||
‘dpkg -i *.deb’
|
||||
you will get some error messages, which can be ignored.
|
||||
again as root use
|
||||
‘apt-get -f install’ to correct this errors
|
||||
|
||||
3. python 2.7 should already be installed on your system but you may need the following additional python package
|
||||
|
||||
'apt-get install python-tk’
|
||||
|
||||
4. all programms need to be installed as normal user. All these programm are installed the same way:
|
||||
‘wine ‘
|
||||
we need:
|
||||
a) Adobe Digital Edition 1.7.2(from: http://kb2.adobe.com/cps/403/kb403051.html)
|
||||
(there is a “can’t install ADE” site, where the setup.exe hides)
|
||||
|
||||
b) ActivePython-2.7.2.5-win32-x86.msi (from: http://www.activestate.com/activepython/downloads)
|
||||
|
||||
c) Win32OpenSSL_Light-0_9_8r.exe (from: http://www.slproweb.com/)
|
||||
|
||||
d) pycrypto-2.3.win32-py2.7.msi (from: http://www.voidspace.org.uk/python/modules.shtml)
|
||||
|
||||
5. now get and unpack the very latest tools_vX.X (from Apprentice Alf) in the users drive_c of wine
|
||||
(~/.wine/drive_c/)
|
||||
|
||||
6. start ADE with:
|
||||
‘wine digitaleditions.exe’ or from the start menue wine-adobe-digital..
|
||||
|
||||
7. register this instance of ADE with your adobeID and close it
|
||||
change to the tools_vX.X dir:
|
||||
cd ~/.wine/drive_c/tools_vX.X/Other_Tools/Adobe_ePub_Tools
|
||||
|
||||
8. create the adeptkey.der with:
|
||||
‘wine python ineptkey_v5.4.pyw’ (only need once!)
|
||||
(key will be here: ~/.wine/drive_c/tools_v4.X/Other_Tools/Adobe_ePub_Tools/adeptkey.der)
|
||||
|
||||
9. Use ADE running under Wine to dowload all of your purchased ePub ebooks
|
||||
|
||||
10. for each book you have downloaded via Adobe Digital Editions
|
||||
There is no need to use Wine for this step!
|
||||
|
||||
'python ineptpub_v5.6.pyw’
|
||||
this will launch a window with 3 lines
|
||||
1. key: (allready filled in, otherwise it’s in the path where you did step 8.
|
||||
2. input file: drmbook.epub
|
||||
3. output file: name-ypu-want_for_free_book.epub
|
||||
|
||||
Also… once you successfully generate your adept.der keyfile using WINE, you can use the regular ineptepub plugin with the standard Linux calibre. Just put the *.der file(s) in your calibre configuration directory.
|
||||
so if you want you can use calibre in Linux:
|
||||
|
||||
11. install the plugins from the tools as discribed in the readmes for win
|
||||
|
||||
12. copy the adeptkey.der into the config dir of calibre (~/.config/calibre in debian). Every book imported to calibre will automaticly freed from DRM.
